Information encryption using pseudorandom gaussian sequences

Abstract

The rapid progress of the electronic telecommunications has contributed to the development of the innovative methods of encoding, encryption and transmission of information, including the cryptographic techniques. The cryptographic techniques of information security in its transmission are the most stable and secure.

The article suggests an algorithm of the information encryption using sequences of pseudorandom real numbers distributed according to Gauss law, which is a good model of noise. The encryption algorithm is based on the pseudorandom key guns, which are based on two linear congruous generators of pseudorandom sequences.

Practically, the algorithm was implemented in the software environment Delphi 7.0. The effectiveness of the algorithm was tested using a quantitative index of the correlation coefficient, the range of which is 0,01 ÷ 0,06 for the encrypted image. The results indicate the high cryptographic security of the suggested algorithm
